Re: Slow Progress is better than No Progress.
It could be a very long story describing how flat tappet cams are made but the short of it is the cam lobe is machined to help spin the lifter in the lifter bore. If the lifter stops turning in its bore then the cam lobe and lifter bottom will destroy itself.
Forgot to mention that the offset lobe to lifter bottom is what helps turn the lifter. As the cam lobe goes up and down the offset lifter will turn.
